similar to: In reply to: What is best way of managing isolated network environment?

Hello, We need to manage isolated network environment so that even though host name and ip address could be same, but they are located in isolated network environment so that?s not a problem. However, that would be very challenging to build a server in such an isolated environment. For example, we could do kickstart to build a server in non-isolated network environment, but for isolated one, we

Without context it's impossible to make firm statements but, having gone through this a while back (and discovering that less than 1 percent of an examined list of connections couldn't support current ssl - mainly Apple hardware), who do you want to protect? Is it the minority who won't/can't upgrade or the majority who have? And, do you have to protect yourself from liability

There may be ways to force NIC naming, I've done so but only on Ubuntu so you'll need to do the research if it's important to you. Things to look for based on my experience: 70-persistent-net.rules, net.ifnames=0, biosdevname=0. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of Nicolas Kovacs <info at microlinux.fr> Sent: Sunday,

Hi, I try to configure a kvm with a NIC, but no attached network to this NIC. I tried following methods: 1. Create a generic ethernet connection I configured the VM with following interface section: <interface type='ethernet'> <script path='/root/noscript.sh'/> <target dev='myvm_nic0'/> <interface/> The script /root/noscript.sh

I want to create a network like this: Internet -- physical router -- host (network 192.168.178.x) -- virtual machine dmz -- eth0 (connected to pyshical router) -- eth1 (connect to isolated network 10.0.0.x) -- virtual machine www - eth0 (connect to isolated network 10.0.0.x) [image: network design]

Linux bind mounts can mount a file over another file (plus there's overlay filesystems), so it's possible to replace a binary even on a read-only device. -- Chris Adams <linux at cmadams.net>

Hi Leroy, How I can confirm that during rsync transfer corruption are not encountered? Thank you in advance.

Hi @all, I'm having trouble to realize my use case and hope somebody could help me. # Use case For a home lab I want to deploy several guest domains.

I realize this shouldn't happen, the file is a tgz and isn't being modified while being transmitted. This has happened maybe three times this year and unfortunately I've just had to deal with it rather than invest the time to do the research.

Lesson learned. I think I had the same IP address assigned to my VM router as I did the Host.

I'm trying to migrate my VirtualBox test lab to KVM. In my VB configuration, I have several VM routers with 4 interfaces each. Each router has a bridged interface which connects them all together and to the outside world. I have servers/clients dispersed on each of the other private (Isolated) segments that use the routers as default gateways. In trying to make this work, I used Virtual

Even ff 45 (?) from CentOS5 will happily access a TLSv1.2-only server. The problem is user that have old versions of software installed with no TLSv1.2 support. SVN, python 2.7 scripts, etc.

Hello, we are currently managing access permissions through classical user-group-others permissions on a multi-petabyte directory tree with partially very deep and broad directories. Projects are represented by directory trees and mapped through GIDs. Lately we had lots of "singular" permission request (one single user needs access to a single dataset but should not be able to

Thank you! I am still playing with KVM, and will more than likely setup my lab as you suggest in order to isolate the guests from the host.

Linux kernel is already containing chunks of code related to systemd/firewalld and friends. One can disable stuff during kernel build, but the result it still is not like
